you guys see the top secret supra on ebay?

[Dylan JZ]

thought it was pretty cool just passing through the pages to see the GT-300 is once again for sale.. might be repost but anyways.

wtf? 1980 toyota supra? looks like a mk4 to me, and a 3sgte? fishy? me thinks so.

nvm about the 3sgte...but why?

because its lighter, put the engine behind the front axle and gave the car a 50/50 weight balance IIRC.. plus it revs to the high heavens and its pretty cool to say you have a 700hp 3s under the hood, especially to those with a 2J haha. Thats pretty much how I figure Nagata-san saw it.

and 1980? it says "1995.." so wtf

[Big Wang Bandit]

Such a crazy car.

do want

[ERA]

S'gotta nice butt.

[Wills7MGTE]

I'd still have to respary it Black when I got it

[JASONA70]

the 3s looks so tiny in the engine bay!

[suprahero]

There's no way that's a 1980 model toyota.

[MK3.0dudeman]

now thats a bad ass supra!

top secret builds some great cars.

I like this one more than there V12 supra.

[supraman7mgte]

all those ponies from a 4 banger? wow

[cartel1_950]

1980???? and i don't know if i'd swap out a 2jz for a 3s but thats just me

[Dylan JZ]

you would if you had the money to do what they did.. the volumetric efficiency of the 3s is insane. less weight and puts the engine behind the front wheels. the 3s is good and long as you can keep it in its powerband.

[Rennat]

and in case you didnt notice it dropped the weight to 2700lbs... thats DAMN good for a supra. so 700hp + a LOT less weight. i bet it would pick on a lot of its brothers with 2jzs.

well, some of that is weight savings due to removing sound deadening etc.. but you're right, most of it is credited to the motor.

[Rennat]

if you think about it. a 2jz supra with 700hp at the crank. vs this supra. i think it would be hilarious to watch.

they knocked off a 1/3 of the long block weight just by switching to a 4 cylinder.

yep.. IIRC the 3s is 86x86 perfect square same as the 2J so to think of it as such is funny. a smaller version that is, also the precursor some say..

[Rennat]

no no no, the 7m was the precursor... people just dont wanna admit it. haha

and if its really 86x86 like the 2j, then thats pretty cool. toyota was pretty smart.

[Zumtizzle]

Okay All of you are wrong.

I know for a fact that motor has a 5S-FE crank, thus making it a stroker 3S! ;)

lol, I knew.. what are you getting at? my argument was for the 3s in general. Then again I think perhaps that wasn't aimed at anyone in general.

[Zumtizzle]

The 2JZ was designed by a Firm In Germany and the 3S is a Yamaha Design, (kinda like a 7M head and a 4A style block.) ;)

really? do you have a link to a site that talks about this? i would love to read about this.

This is a very common misconception.. True that it was outsourced for refinement, but you forget one thing, we already had the 1JZ which is identical component wise in many ways to the 2JZ. There are definitely changes but there are also similarities.

I would like to see proof that anything other than the head is yamaha design on any of these motors.

[Bigzavs]

i wonder where Norway, Japan is?


look at the location listed on the page

cars in norway, the company auctioning is in JP.

I'll do one better.

^the supposed firm that refined the Yamaha 1JZ into the 2JZ Monster. :evil2:

If you put the 1JZ longblock alongside the 2JZ. MANY MANY similarities.

Except the crank and exhaust valves. ;)

I wish proof could come up. I'm just going off of what some OG supra owners have told me.

yep.. they certainly did a decent job I'll give them that. I've always wondered if the sequential twins was their design. I know toyota manufactured everything in the blueprints but what precisely they designed would be interesting (to me at least).

your response was not what I expected, very nice. you're correct for the most part I just figured you were like some that claim that firm revolutionized, rather than just small improvements here and their that ended up really benefitting the motor.

You know we had a long debate about that in a SF chat, but we all came to an agreement, sequential < parallel. ;)

But it does have toyota vsv's and if you put the 1JZ and 2JZ clusterfuck of twins next to each other besides the vsv's and the "flapper" nothing else besides size is really there difference wise.........

agreed. I think I vaguely remember a thread of that sort.

[Zumtizzle]

So if someone really wanted to know the R&D of the 2JZ. I bet i could ask one of my German friends to call and speak to an engineer there and see what actual blueprints or logs look like. (if they release that info, or hell someone even remembers the 2JZ. ;)) We're talking almost 18 years assuming improvements of the Yamaha design at Johann A. Krause Maschinenfabrik GmbH began in 1990, when the 1JZ debuted in the A70. But at this point, i'm just happy to know what little of the 1JZ to 2JZ transformation i know.
